I am looking into getting a MEVI and in the future, I am definitely getting true boost (not NAWZ like I have now). Does the MEVI benefit the turbocharged and supercharged Maximas to the extent that it is still worth buying? Thanks.

 

20 - 60 some higher horsepower at the higher end of RPM band.....Iansw I beleive dynoed his after and saw a great increase as well as MardigrasMAx.

ask Sprint

 

Meaning????....

 

Sprite will chime in with his theory soon enough... this thread is SpriteMax bait.

 

:song: Oh little Spritey where are you, we love you :end song:

 

Ok I was thinking about Sprints theory a bit the other day. I know he was saying that the XXHP it gains or so is not justifyable by the cost since when he is going to be turbo'd just a level up on the boost controller will make the XXHp itself. Granted this is true no argument there from me.

But my question is this now, wouldn't it be better in some ways because it will give you fuller power on the turbo right up to redline? Will a turbo still get the drop in power at say 5700 or so that you do NA or with an SC?

Not trying to start a big debate just something I was wondering.

i am not going to get flamed in 3 straight threads.. so everyone just go ahead and buy it

 

Sprint, I haven't heard your theory. I am interested in hearing it. I promise, I won't flame you, and so does everyone else..... . I just want to make sure I don't buy something that won't benefit me in the near future.

 

3 straight threads? Is that all?

my theory is.. for a TURBO the air needs to get to the intake manifold as quickly as possible because the air needs to be recycled for the exhaust for the turbo.. its less beneficial for a turbo car to use a VI than a NA car..

my other theory is.. even if the VI gave the turbo car 40 fwhp more why would you waste $735 on that when you can just turn up the Boost Controller..

my other theory is that.. NA cars make more fwhp on a VI than SC cars do.. on a proven dyno.. so obviously the VI is a better NA mod..

my other theory is that if you have a SC ... get a VI because the extra 40 hp will come in handy.. not like a Turbo car who can turn up and down the boost..

flame on

 

hehe Sprint really is not embaraased about getting flamed. It comes with the territory after a while. I will try to search for the thread where he really got into it. Let me ttake a look.

You can only turn up the boost so much... but no matter what you do, the top end is going to get choked off because of no VI. Just look at Nigel's dyno graph (371 hp, 369 tq).

 

That is exactly what I was trying to ask.

The truth about turbos, one and for all...

 

 

exactly why i didn't want to post in this thread.. but like i said.. whatever happens happens

and our turbo's are good for 30 PSI.. we will go BOOM long before we run out of turning up the boost

 

I agree with Kev the VI just helps expand the HP curve and give you more of a plateau for a boosted car. I mean it just gives you more or a power band...no severe drop off. I know Nigel has one just don't think he has been able to dyno it yet or might have a small vacuum leak somewhere he is trying to fix. But I can't wait to see his dyno graph just to see what type of numbers a turbo gets with the VI, because I know that is why Nigel was buying the VI so he wouldn't have that drop in power in the upper RPM range.

But a theory I have is that possibly the VQ30DET collector might work better for boosted cars because you don't have the long runners that you have to go through. But, it needs to be dyno tested which I know that Avalon42 is going to try it out once he gets his car's internals done. That is just another thought.

Thanks for the reply John. Is the VQ30DET collector a "straight" bolt-on to our car and what exactly is it lol. Thanks again.

 

erik we can compare notes in a few months... sound good?

 

Here is the parts picture for it http://www.unm.edu/~garbear/Pictures...emanifold2.BMP
It bolts on directly to our intake manifold, but the only thing that I'm not sure about is if our throttle body will bolt up directly to it...I'm pretty sure it does just with what I seen from Tilley99 (I think that was his name) had done. Because he took the basically everything from the VQ30DET and put in on his car. Hopefully when Avalon42 gets his car back together...we'll know for sure what needs to be done...but it is relatively cheap ($500) with no added RPM switch or anything for the VI to turn on. But this is a theory I hopefully it will turn out to be benefitial to boosted cars, but now we are playing the waiting game.
